Serial No. 762,504.

To all 107mm t may concern.'

Be it known that I, IVILLIAM H. KLAUER,

a citizen of the United States, residing at Dubuque, in the county of Dubuque and In forming the culvert of my invention, I do not flange the longitudinal edges of the sections but provide flanged strips attachable to the sections, and flanges wholly coin- State of Iowa, have invented certain new ciding when attached when the half secand useful Improvementsu in Culverts, of tions are placed together.

which the following is a specification. Referring to the accompanying drawings, My invention relates to culverts. 2 are corrugated culvert sections, each sec- `More particularly my invention relates tion forming substantially one-half of a cylto a nestable culvert. y inder formed by the union of two sections, AThe object of my invention is to produce their longitudinal fedges 3 and 4 being culvert sections susceptible of' union to any length desired without the use of bolts, rivets, or clamping bands. Y

adapted in their each other hereinafter proper union, to overlie and to be Joined in the manner described. To provide for an in contact, thus leaving a V space between tions with the flanged portions resting' upon the flanges.

the laterally extending flanged portions 8b of flanged plates 8 and then the edges Se may be bent downward into the position shown in Fig. 3 or they may be simply struck inwardly toward the body of the culvert, thus forming a secure interlock. l

It desired, culvert sections, that is the upper and lower sections, may be arranged in break-joint relation with the same good results attending and without any modification in form, principle, or construction from that herein disclosed.

In the drawings I have shown flanged strips 7 and S upon the joined cylindrical sections overlapping slightly and in practice I prefer this form. However, in practice, the strips may be made to abut endwise, with good results and without departing from the spirit of my invention.

Having thus described my invention, what I claim is 1. As an improved article of manufacture, a pair of corrugated culvert sections adapted to be united to form a substantially cylindrical body with longitudinal edges respectively of the sections designed to overlie each other, a pair of angle strips disposed one upon each edge of one section and extending longitudinally thereof, a pair of angle strips disposed upon and in rear of each edge of the matching section longitudinally thereof provided with upturning locking flanges.

copies of this patent may be obtained for five cents each, by addressing 2. A' substantially cylindrical culvert section comprising two above the other, an interlock Jfor said members comprising pairs of angle strips, one pair disposed at the longitudinal edges of one section and the other pair at and in rear of the longitudinal edges of the other sec-V tion,V the latter having upturned'members adapted to be struck over in Contact relation with the flanges of the first named section.

3. In combination,` semicylindrical sections adapted to be disposed relatively one above another and with their longitudina edges overlying each other, sets of angle strips for each sectio-n secured respectively one angle strip of one set at each longitudinal edge of one section, and strips of the other set at and in rear of the edges of said section.

4. A culvert, comprising two sections, their longitudinal edges overlying each other, two sets of angle strips, one at the edge of one section and the other at the edge and in the rear of the other section, portions o said angle strips being folded together edge to edge and lip to lip.

In testimony whereof I have affixed my signature in presence of two witnesses.
